====== Role Assignment ====== [[public:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]] ===== Discussion ===== A Role Assignment associates an entity with a [[public:99_annexes:annex-b-terms-and-definitions:r:role|Role]] in a specified context. A Role defines a function, capacity, or position that may be performed or held. A Role Assignment identifies the entity that performs or holds that Role in a particular activity, transaction, contract, agreement, process, situation, or regulatory context. The entity may be a [[public:99_annexes:annex-b-terms-and-definitions:p:party|Party]] or another entity permitted by the applicable model. When a Party performs a Role, the Role Assignment provides the relationship through which the Party participates in the specified context. A Role Assignment may identify: * The entity performing or holding the Role * The assigned Role * The context in which the Role applies * The effective period of the assignment * The authority or basis for the assignment * A represented Party, when the entity acts on behalf of another Party * The status of the assignment * Applicable constraints * Evidence supporting the assignment * Provenance describing how the assignment was established The Role Assignment is distinct from the entity, the Role, and the context. A change to a Role Assignment does not change the identity of the entity or the definition of the Role. ===== Definition ===== > //relationship that associates an entity with a [[public:99_annexes:annex-b-terms-and-definitions:r:role|Role]] in a specified context// ===== Source ===== Adapted from: * [[https://www.omg.org/spec/Commons/1.3|OMG Commons Ontology Library, Version 1.3]] * Relevant ontologies: Roles and Compositions, and Parties and Situations * Relevant concepts and relationships: Role, Party Role, is played by, has party role, and applicable period * OMG File ID: formal/26-06-05 * Retrieved: 2026-10-08 The term //Role Assignment// names the explicit relationship structure used by this corpus. OMG Commons provides the underlying concepts of Role, performer, context, and applicable period but does not define a concept having this exact name.

The applicable Role Assignment identifies: * Example Bank as the Party performing the Role * Counterparty as the Role * The FX Trade as the context * The period during which the assignment applies If Example Bank is also responsible for regulatory reporting, that responsibility is represented by a separate Role Assignment identifying Reporting Counterparty as the Role and the applicable reporting context. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
